How is the ETC toll calculated on highways now?

[McJeffrey]

Here are the ETC highway toll rules: 1. For ETC vehicles, the toll amount is first rounded using the "round down below 0.5" method (amounts with decimals below 0.5 are rounded down, while decimals equal to or above 0.5 remain unchanged), then a 5% discount is applied, and finally rounded to the nearest cent. MTC vehicles still follow the "round to nearest yuan" rule. 2. Before the adjustment of ETC vehicle billing rules, the toll amount was calculated by first rounding to the nearest cent, then applying a 5% discount and rounding to the nearest cent again. According to the adjusted billing rules, some ETC vehicle tolls are now calculated by first rounding down below 0.5, then applying a 5% discount and rounding to the nearest cent, resulting in slightly lower tolls compared to the previous rules. 3. Compared with MTC vehicles' "round to nearest yuan" method, ETC vehicles first use the "round down below 0.5" method, then apply a 5% discount and round to the nearest cent, making their tolls lower than MTC vehicles. This adjustment in billing rules solves the issue where ETC tolls on some local road sections were higher than manual toll collection when directly calculated to the nearest cent, further reducing travel costs for citizens on certain routes.
